PERCOLATO R.

SPECIFICATION forming part of Letters Patent No. 436,199, dated September 9, 1890.

' Application filed June 5 1890- Serial No. 354,393. (No model.)

To all whom it may concern.-

Be it known that we, WILLIAM D. \VAR- NICK and CHARLES E. CUNNINGHAM, citizens of the United States, residing at Baltimore, in the State of Maryland, have jointly invented a new and useful Improvement in Percolators, of which the following is a specification.

Our invention relates to percolators intended for pharmaceutical purposes, and has for its object the provision of means whereby substances may be graduatingly percolated in closed receptacles.

The further object of our invention is the provision of means whereby the dispensingbottle or other receptacle may be readily lifted up to and withdrawn from the source of supply.

Our improved percolating device is hereinafter fully described, illustrated in the drawings, and specifically pointed out in the claims.

Referring to the accompanying drawings, wherein like letters and figures of reference point out similar parts on each figure, Figure 1 is an elevation of our improved percolator, showing a dispensing-bottle elevated and having the stem of a funnel within its, mouth. Fig. 2 is a sectional view showing the bottle moved downwardly in position for withdrawal from its stand. Fig. 3 is an enlarged detail view of an elastic collar and closing device adjustably mounted on the funnel-stem.

In the drawings, A is a table or stand of any suitable configuration having legs a for the purpose of keeping it elevated from the floor, counter, or other support; a required distance to admit of the downward passage therethrough of ratchet-bar R. Upon the upper surface a of the stand are socketed plates 1, which receive the lower ends of vertical rods 2, detachably held therein by screwbolts 3. .These rods support at their upper ends a board B, which, by suitable keys or bolts, is held in a horizontal position. Said board has an opening 1), through which the upper end of the dispensing-bottleD or other receptacle will extend when moved upwardly in the position shown in Fig. 1.

O is a movable shelf provided at either end with an eye 0, through which the rods 2 are inclined obliquely, as plainly seen in the drawings, thereby providing an aligning seat for the tapering chamber of funnel F. The

yoke-frame is sustained in place by means of screw-nuts n. The standards S are each bent outwardly away from the yoke-frame, forming lateral arms .9, and from thence have upward verticalscrew-threaded sectionss,which pass through orifices of the funnel-cover E, which, by means of thumb-screws 6, can be maintained firmly against the upper peripheral edge of the funnel. The cover E is adapted to securely close the upper open end of the funnel, and in order to make the closure perfect is provided with an under yielding sheathing c. This cover has an opening 4, through which the material to be treated is introduced into the funnel. When the necessary quantity has been deposited, said opening is closed by means of alid 5, pivoted at 6, to swing horizontally over the opening 4:. Said lid is supplied with suitable means for controlling atmospheric pressure. It may be a stop-cock '7, as shown in Fig. l, or plug 8, as shown in Fig. 2, a valve, or any analogous device for such purpose, which, in combination with preconcertcd escape controlled by the elastic collar G-at the bottle-mouth, willallow the menstruum deposited within the funnel to percolate with more or less rapidity, as desired, and as the nature of the material under treatment may require.

R is a ratchet-bar having upon one of its sides teeth 9. Its upper end is firmly secured to asocket-plate 10, attached to the under side of movable shelf O and extending from thence vertically through the squared orifice of the boss 12 of casting 11 attached to the upper surface a of table A. Journaled in cars 13, uprising at one side of said casting, is a bell crank lever L, one end of which constitutes a pawl 14:, which extends to and meshes with shown in said figures, wherefrom it can be readily removed. Conversely, when another vessel is substituted, it is placed upon the shelf, which is then moved upwardly until connection is made with the funnel. It will be understood that the projection of the shelf upwardly to any height can be effected by means of the spring-controlled pawl, which will mesh with a ratchet-tooth at any point where the shelf is brought to rest by releasing pressure of the handle 1. downward progress of the shelf is regulated by means of limiting-posts l6, uprising from the table, which posts should be of length slightly extending above the upper plane of the lever L and its connections, whereby as said shelf is moved down it will be brought to rest upon said posts.

In lieu of the posts 16 said shelf may be stopped by means of flanges 17' upon the rods 2, as illustrated in Fig. '2.

G is an elastic movable collar encircling the eduction-spout of the funnel and movable thereon. shown in Fig. 1, there will naturally be a circumferential space, forming a vent between the bottleneck and that portion of the funnel-stem inserted therein, which can be partially or entirely closed by moving said collar downwardly toward the induction-opening of thevessel D. As the diameter of said opening and eduction-spout will vary according to the relative circumferential size of these juxtaposed members, it will be readily understood that the vent can be controlled by moving the collar G downwardly to seal said vent to any required degree. When the dispensing-vessel is removed from the funnel, as shown in Fig. 2, the eduction end of the funnel-stem will be open and unprotected, and the contents thereof will flow outwardly therefrom. It is usual in analogous devices of the character described to close such orifice with an ordinary cork. For stopping such outflow we provide a spring-trap g, hinged to one side of the collar, which, as soon as the dispensingvessel is withdrawn from the funnel,is adapted to be turned downwardly and folded horizontally under the funnel-spout, whereby the under opening thereof will be completely closed.

By reference to the drawings and description herein it will be seen that thevarious members of our improved percolator are all detachably mounted above the table A and The extreme} When the device is in the position can be disconnected by unscrewing the several nuts and bolts employed to hold the device in operative position shown in the drawings. We thus provide a knockdown percolator that can be disconnected and compactly packed for transportation purposes, the several members being readily adjusted by persons unskilled in mechanics.

Having thus fully described our invention, what we claim, and desire to secure by Letters Patent of the United States, is-

1. A percolator having mounted on a suitable support vertical rods passing through opposite eyes of a movable horizontal shelf adapted to sustain a receiving-vessel, said rods at their upper ends holding in suspension board B, having central opening I), said board provided with standards S,which,after passing through opposite ends of yoke-board Y, are respectively bent outwardly in opposite directions and then extended upwardly to support funnel cover E, said cover adapted to be moved upon the extensions 8' and adj usted thereon by thumb-screws c, all in combination, as and for the purpose intended, substantially as described.

2. The within-described percolating device,- having supported above a horizontal board B, held suspended upon vertical rods 2, a yoke Y, provided with central opening toreceive funnel F, the opening of said yoke having its periphery shaped downwardly obliquely in alignment with the divergence of the funnelchamber, in combination with funnel-cover E, movable vertically upon screw-threaded extensions 8', said cover having central opening 4, provided with horizontally-swinging closing-lid 5, said lid having a suitable valvefor regulating atmospheric pressure, all arranged, as set forth and described, as and for the purpose intended. V

3. A pharmaceutical percolator having a funnel F, removably seated in yoke Y, the eduction-spout of said funnel suppliedrwith elastic collar G movable thereon, said collar having spring-controlled trap g,'adapted to be folded under the eduction end of the funnelstem to close the opening thereof when removed from the receiving-vessel, as and for the purpose intended, substantially as described.

4. The combination, in a pharmaceutical perculator, of a vertically-moving support for the receiving-vessel maintained at any desired elevation through actuation of a springcontrolled pawl interlocking with teeth of a ratchet-bar depending from said shelf,a funnel suspended within a yoke above the shelf, the stem of said funnel supplied with an elastic collar moving thereupon to and from the mouth of the receiving-vessel, whereby the vent thereof is controlled, and a cover for the upper open end of the funnel adjustable thereon'by means 'of thumb-screws, said cover having its lower surface covered with elastic sheathing and having suitable means for admission and exclusion of air to regulate atmospheric pressure, as and for the purpose intended, substantially as described.

5. The within-described pharmaceutical device, consisting of the combination of the following elements: yertical rods 2, verticallymovable shelf 0, board B, yoke-frame Y, standards S, funnel F, coverE, and stand A, all arranged to be severally connected and disconnected, as set forth,to comprise a knockdown percolator, substantially as described.
